Same contest goes on around here except they use water squirt guns and there are teams of 2 students. Actually any form of water spray qualifies as a “kill”. Garden hoses, water balloons and so on. If one of the team members gets “shot” then the whole team is eliminated. It’s been 15 years since my boys were in high school, but what I remember most was the constant looking over their shoulder paranoia wondering who was out to get them. As far as participation goes, it seemed like there were 30-40 teams out of a graduating class of 250.
